Not only is Yellowstone National Park the place to go for geysers, NPS said, “A mountain wildland, home to grizzly bears, wolves, and herds of bison and elk, the park is the core of one of the last, nearly intact, natural ecosystems in the Earth’s temperate zone.” There is such huge animal diversity because of the Greater Yellowstone Ecosystem. Regarding the mammals in the park, the 2013 Yellowstone Trip Planner (.pdf) states: “Keep your distance. Federal regulation requires you to stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from all other wild animals, such as bison, elk, bighorn sheep, deer, moose, and coyotes.” The Yellowstone National Park Service says of the wildlife, “Yellowstone is home to the largest concentration of mammals in the lower 48 states. 67 different mammals live here.” These pictures show the diversity and a wide variety of magnificent animals of Yellowstone.

He grazed towards my car then gave me a quick look, so I was able to take this from about 20 yards away.” Yellowstone Park Service explained, “67 different mammals live here, including grizzly bears and black bears.” Photo #1 by Pat Gaines

Many of these photos were taken during a cruise to Glacier Bay, others from the air, but Glacier Bay National Park and Preserve offers all kinds of adventures. What starts as a loud crack like a rifle shot is also a sign of icebergs being born at Glacier Bay as glaciers break off or calve. The National Park Service asks, what do you want to do and how much time do you have to do it in? “Covering 3.3 million acres of rugged mountains, dynamic glaciers, temperate rainforest, wild coastlines, and deep sheltered fjords, Glacier Bay National Park is a highlight of Alaska’s Inside Passage and part of a 25-million acre World Heritage Siteone of the world’s largest international protected areas. From summit to sea, Glacier Bay offers limitless opportunities for adventure and inspiration.” Glacier Bay National Park and Preserve also has the 3rd highest elevation of all U.S. National Parks. Here are some of the gorgeous ancient glaciers, photos capturing the glaciers calving and the birth of icebergs, wonderful wildlife, and spectacular scenery of Glacier Bay National Park and Preserve, Alaska.

Waterfall beneath Lamplugh Glacier, one of the glaciers at Alaska’s Glacier Bay National Park and Preserve. While there are many reasons that this park is special, one of them is that there are no roads that lead directly to Glacier Bay. The park is mostly water, so most visitors see it from a cruise ship with thousands of other people. But boats come in all sizes and some adventurers see Glacier Bay from a kayak.

If you have a dog, then you know he or she is a loyal part of your family. When some folks deck the halls, they also deck their dogs in holiday accessories. Luckily, most of us have dogs that will do about anything for treats and possible Christmas gifts. Unlike the sometimes destructive cats vs. Christmas trees, most dog owners capture shots of their beloved pet being cute and sweet. These photographers share their descriptions and their cute doggies’ photos. [48 Photos]

Cats seem to think we put up Christmas trees just especially for them. Some cats are satisfied under the tree, but some cats are sure you put that tree up for them to climb. That is the case for these photographers who will tell you about finding their cats in Christmas trees. [42 Photos]

For people who are animal penguin lovers, besides Tux lovers, here are the tuxedo-wearing waddlers that dwell primarily in Antarctica. While penguins don’t fly, they can spend as much as 75% of their time at sea. All penguins give birth to their chicks on land or on sea ice. Because penguins so incredibly cute, they are often depicted on holiday ornaments and in happy animation movies. We love these penguin pics! [41 Photos]

What can you get ‘for free’ to virtually wish Linux lovers a happy holiday season? How about a hat tip to Tux, the cute little iconic penguin mascot representing free and open source Linux? This Tux probably is not your grandma’s penguin. Here’s Tux as seen traveling and bashing shells ‘in the wild.’ Cats and dogs love Tux. In fact, there are tributes to the Tux mascot via food, toys, and even from a few future Linux hacker babies. Tux inspires art like digital wallpapers as well as Tux graffiti. We’ll toss in a few interesting Linux facts and hopefully dear Linux lovers, you will at least smile and remember that it’s the thought that counts? Smile and have a great day! [69 Pics]

Tux in A Holiday Dream. Unless your granny bashes shells, then this is probably not your grandma’s penguin. Once upon a time, James Hughes called this penguin “Tux;” he said that it stood for “(T)orvalds (U)ni(X).” This is Tux the penguin, the official mascot for Linux. There are many different Linux distributions, a bit like operating system flavors, that utilize the Linux kernel, but even if displayed in various styles, Tux is iconic for Linux distros and free, open source software.

In the winter, over Europe, massive starling flocks, from thousands to millions of birds, swarm, swoop, shift, swirl and twirl, moving as one while performing amazing aerial acrobatics. Although a previous Love These Pics post was full of bird flocks and flying swarms that seemed to be attacking like Hitchcock’s The Birds, some were, in reality, a starling murmuration. This extraordinarily beautiful ballet at dusk is a pre-roosting phenomenon known as starling murmuration. Although this is science, the phenomenon is more math and physics than biology. The ‘Black Sun’ is hypnotic to watch as the starlings fill the evening sky, twisting and turning in a incredible and unpredictable waltz. [37 Photos, 13 Videos]

500 – 700 million years ago, even before dinosaurs roamed the Earth, jellyfish were drifting along on ocean currents. Jellies are among the most spectacular and mysterious marine species in the world. They are the oldest multi-organ animal and have morphed into more than 2,000 different jellyfish species. Some live in freshwater, but jellies can be found in every ocean. Some sea jellies survive close to the surface while others dwell in extreme depths, glowing with bioluminescence in the pitch black water near the bottom of the ocean. Many scientists and deep ocean explorers expect to discover countless more beautiful jiggly jellyfish as they explore deep sea canyons, and other extreme water conditions near underwater volcano vents and in the harsh frozen temperatures of arctic waters.

Jellyfish go with flow and have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. Few marine creatures are as mysterious and intimidating as jellyfish. Though easily recognized, these animals are often misunderstood. Sea nettles often have riders on their bodies, sometimes offering a place for small living organisms to be able to move around and sometimes being the food source for the organism. There is a reddish tint on the bell of the Pacific Sea Nettle or West Coast Sea Nettle which can span over 3 feet. This is a distinctive characteristic along with maroon tentacles that identify this particular species of jellyfish. The tentacles can be up to 15 feet long. Photo #1 by luna

When the woods is Brothers Grimm scary was sort of far out, fun and freaky, so here’s another peculiar collection where spectacular flocks inspired some photographers to think of Alfred Hitchcock‘s The Birds or Edgar Allen Poe‘s The Raven. Flocks can be beautiful, peaceful but then . . . when the birds are scary? [60 Photos, 2 Videos]

Fall seems to officially be here, based the feverish pace of squirrels preparing for winter. When we went out and about to enjoy autumn, there was one constant other than the beautiful foliage changing colors, and that was the squirrels gathering acorns and other nuts. Everywhere we went, the squirrels were acting squirrelly, running around with nuts in their mouths, performing ninja-like gymnastics in tree branches, or digging to hide their winter stash. There are about 285 species of squirrels and the antics of these furry cute critters are fun to watch and to photograph. [60 Photos]

Hoarder. With those long hairy ears, this squirrel might be mistaken for a bunny at first glance. In the fall, the squirrels seem to understand that very soon it will be difficult, if not impossible, to gather food, so food collection advances to a nearly feverish pace. They bring even more food into their homes, with tree squirrels stocking up inside hollow trees and ground squirrels digging new chambers for the extra storage room if needed. They then stash more food near their tunnels or tree homes. Photo #1 by Poppy

Happy World Animal Day! Way back in 1931, a convention of ecologists in Florence, Italy, decided that there should be an annual World Animal Day to pay tribute to all animal life and the people who love them. It is also a way to highlight the precarious situation of endangered species worldwide. It was decided that October 4, the feast day of Francis of Assisi, a nature lover and patron saint of animals and the environment, should be chosen as World Animal Day. Some churches will bless animals on the Sunday closest to October 4. We love animals and the environment, and decided to salute animals via an ABC’s of wildlife. [27 Photos]

Fall and its brightly colored foliage has arrived. So here is a mixture of animals, autumn and quotes about this season.

“Autumn, the year’s last, loveliest smile,” ~ quote by William Cullen Bryant. Like some people, some animals love autumn. Red fox with a mouse in the beautiful and bright foliage of the forest during the fall season. Photo #1 by KP
